Figure 1. Genetic variation in seven traits amongst open-pollinated families of Eucalyptus globulus grown in two Tasmanian field trials.

The geographical source of each locality in Victoria, Tasmania and the Bass Strait islands is shown. Symbols represent the genetic-based variation in foliar concentration of six chemical constituents (A – F) and DBH (G, H) as shown in the left of the figures. Triangles indicate relatively high values, with larger triangles the highest values. Circles indicate relatively low values, with larger circles the lowest values. Results averaged across two common environment field trials for the chemicals; separate figures for each site for DBH due to a significant site*sub-race interaction (Table 2). Sub-race codes as in Table 1.
